Realistic display of volumes

We present a method for recursively rendering a realistic image of a volumetric dataset consisting of a mixture of sampled and synthetic objects. We describe several volume visualization tools that are based on the use of recursive ray tracing. These include shadows, mirrors, specularity, and constructive solid geometry. We discuss several ways to enhance our method both in terms of image quality and rendering speed by introducing the principles of adaptive traversal and probabilistic rendering.
